Description

本発明は、河川などの流水に浮いた状態で配設される網場や油フェンスなどの浮遊体に関し、特に、水位の変動に追従して浮遊体が昇降する浮遊体装置に関する。   The present invention relates to a floating body such as a net or an oil fence disposed in a floating state such as a river, and more particularly to a floating body device that moves up and down following a change in water level.

例えば、河川などに設けられた取水口スクリーンに流木や塵芥などが溜まるのを防止するために、網場が配設されている。この網場は、取水口スクリーンの前方(上流側)に水に浮いた状態で配設され、流木などの流れ込みをこの網場によって留めることで、流木などが取水口スクリーン側(下流側)に流れ込むのを防止するものである。このような網場には、水位の変動に追従して昇降するとともに、網場に付着した流木や塵芥などを容易に取り除けるようにした浮遊体装置(網場装置)が知られている(例えば、特許文献1参照。)。   For example, in order to prevent driftwood, dust, etc. from accumulating on a water intake screen provided in a river or the like, a net is provided. This net is located in front of the intake screen (upstream) in a state of floating in the water, and drifting of driftwood etc. is stopped by this net, so that driftwood etc. is on the intake screen side (downstream) It prevents it from flowing in. In such a net field, a floating body device (net field device) is known which moves up and down following fluctuations in the water level and can easily remove driftwood and dust attached to the net field (for example, net field device). , See Patent Document 1).

この浮遊体装置は、一対の支柱の間に網場の両端部が昇降可能に張設され、網場の一方の端部には滑車が取り付けられている。この滑車にウインチ側ワイヤ(ロープ)がかけられ、ウインチ側ワイヤの一端部側が、支柱よりも上方に設けられたウインチによって巻き上げ、巻き下げ可能となっている。さらに、ウインチ側ワイヤの他端部に輪状部が設けられ、この輪状部に着脱可能な第1フックをバランサ側ワイヤを介して常時上方に引っ張ることができるバランサが設けられている。そして、水位が変動した場合には、網場が支柱に沿って昇降することで水位に追従する。この際、ウインチ側ワイヤの他端部側がバランサによって引っ張られているため、ウインチ側ワイヤにたるみが発生せずに、ウインチ側ワイヤの巻き上げ時の動作不良が防止される。また、網場に付着した流木や塵芥などを取り除く際には、ウインチ側ワイヤの輪状部を第1フックから外し、ウインチ側の架台に付設された第2フックに係止する。この状態で、ウインチによってウインチ側ワイヤを巻き上げると、網場の一端部が支柱に沿って上昇し水面から離れる、というものである。   In this floating device, both ends of the net are stretched between a pair of support columns so that the net can be moved up and down, and a pulley is attached to one end of the net. A winch side wire (rope) is hung on the pulley, and one end portion side of the winch side wire can be wound up and down by a winch provided above the support column. Further, a ring-shaped portion is provided at the other end portion of the winch-side wire, and a balancer is provided that can always pull upward a first hook that can be attached to and detached from the ring-shaped portion via the balancer-side wire. And when a water level fluctuates, a netting field follows a water level by raising / lowering along a support | pillar. At this time, since the other end portion side of the winch side wire is pulled by the balancer, the winch side wire does not sag, and malfunction during winding of the winch side wire is prevented. Further, when removing driftwood or dust attached to the net, the ring-like portion of the winch-side wire is removed from the first hook and locked to the second hook attached to the winch-side gantry. In this state, when the winch-side wire is wound up by the winch, one end of the net is raised along the support column and separated from the water surface.

特開2004−100169号公報JP 2004-100169 A

ところで、上記特許文献1に記載されているような浮遊体装置では、一対の支柱の間に網場の両端部が張設されているため、支柱と網場とが一直線上に配設されて上流側に臨んだ状態となる。このため、上流側からの流木や塵芥などが、支柱と網場の端部との間に入り込み、さらには詰まってしまい、網場の昇降ができなくなる、すなわち、網場が水位に追従できなくなる場合がある。また、網場に付着した流木や塵芥などを取り除く際(網場を水面よりも上昇させる際)には、ウインチ側ワイヤの輪状部を第1フックから第2フックに掛け替えなければならない。そして、このような掛け替え作業は、水上かつ高所であるため、危険を伴うとともに、多大な労力と時間とを要する。さらに、網場に付着した流木や塵芥などを取り除く際には、バランサ側ワイヤおよび第1フックが未使用な(浮いた)状態となるため、バランサ側ワイヤや第1フックがウインチ側ワイヤなどと絡み、網場の上昇を阻害するおそれがある。   By the way, in the floating body apparatus as described in the above-mentioned patent document 1, since both ends of the net are stretched between the pair of columns, the columns and the net are arranged in a straight line. It will be in a state facing the upstream side. For this reason, driftwood, dust, etc. from the upstream side enter between the support column and the end of the net, and further clog up, making it impossible for the net to move up and down, that is, the net cannot follow the water level. There is a case. Further, when removing driftwood or dust attached to the net (when raising the net above the water surface), the ring-shaped portion of the winch-side wire must be changed from the first hook to the second hook. And since such a change work is on the water and a high place, it is dangerous and requires a lot of labor and time. Furthermore, when removing driftwood or dust attached to the net, the balancer side wire and the first hook are unused (floating), so the balancer side wire and the first hook are connected to the winch side wire, etc. There is a risk of entanglement and hindering the rise of the net.

そこで本発明は、安全かつ容易に浮遊体を水面よりも上昇させることができ、さらには、浮遊体が水位の変動に追従して確実に昇降できる浮遊体装置を提供することを目的とする。   Therefore, an object of the present invention is to provide a floating body device that can raise the floating body above the water surface safely and easily, and that the floating body can ascend and descend reliably following the fluctuation of the water level.

上記目的を達成するために請求項1に記載の発明は、河川などの流水に浮いた状態で配設される網場や油フェンスなどの浮遊体を備えた浮遊体装置であって、位置が固定された固定滑車にウインチのワイヤが掛けられ、このワイヤの自由端部が前記浮遊体に取り付けられ、前記ワイヤを巻き上げおよび巻き下げするウインチ本体と前記固定滑車との間の前記ワイヤに、前記ワイヤを張るのに要する重量を有する移動滑車が上下方向に移動可能に設けられ、この移動滑車の位置を固定する固定手段が設けられている、ことを特徴としている。
(作用)
例えば、流水の水位が上昇すると浮遊体も上昇し、ウインチ本体と固定滑車との間のワイヤの長さが長くなり、移動滑車が自重によって下方に移動するとともに、移動滑車の重量によってワイヤが張られる。一方、水位が下がると浮遊体も降下し、ウインチ本体と固定滑車との間のワイヤの長さが短くなり、ワイヤの移動によって移動滑車が上方に移動するとともに、移動滑車の重量によってワイヤが張られる。また、固定手段によって移動滑車の位置を固定し、ウインチ本体を巻き上げ方向に作動させることで、移動滑車および固定滑車を介してワイヤが巻き上げられ、浮遊体が上昇する。

(Function)
For example, when the level of running water rises, the floating body also rises, the length of the wire between the winch body and the fixed pulley increases, the moving pulley moves downward by its own weight, and the wire is stretched by the weight of the moving pulley. It is done. On the other hand, when the water level falls, the floating body also descends, the length of the wire between the winch body and the fixed pulley is shortened, the moving pulley moves upward by the movement of the wire, and the wire is stretched by the weight of the moving pulley. It is done. Further, by fixing the position of the moving pulley by the fixing means and operating the winch body in the winding direction, the wire is wound up via the moving pulley and the fixed pulley, and the floating body rises.

請求項2に記載の発明は、請求項1に記載の浮遊体装置において、前記浮遊体の前面が前記流水の上流側に位置され、前記浮遊体の前面と対向する前記浮遊体の背面が前記流水の下流側に位置され、前記浮遊体の背面に被ガイド部が設けられ、この被ガイド部を上下方向に案内するガイド部材が設けられ、前記浮遊体が前記ガイド部材に沿って昇降可能に前記被ガイド部が前記ガイド部材で支持されている、ことを特徴としている。
(作用)
流水の水位が変動すると、被ガイド部がガイド部材によって支持、案内されながら、浮遊体がガイド部材に沿って昇降する。
The invention according to claim 2 is the floating body device according to claim 1, wherein the front surface of the floating body is positioned on the upstream side of the flowing water, and the back surface of the floating body facing the front surface of the floating body is the Located on the downstream side of running water, a guided portion is provided on the back of the floating body, a guide member for guiding the guided portion in the vertical direction is provided, and the floating body can be moved up and down along the guide member The guided portion is supported by the guide member.
(Function)

請求項3に記載の発明は、請求項2に記載の浮遊体装置において、前記被ガイド部がリング状に形成され、前記ガイド部材が上下方向に延びる線材で構成され、前記被ガイド部に前記ガイド部材の線材が挿入された状態で前記被ガイド部が前記ガイド部材で支持されている、ことを特徴としている。
(作用)
流水の水位が変動すると、リング状の被ガイド部がガイド部材の線材によって上下方向に案内されながら、浮遊体がガイド部材の線材に沿って昇降する。
According to a third aspect of the present invention, in the floating body device according to the second aspect, the guided portion is formed in a ring shape, the guide member is configured by a wire extending in the vertical direction, and the guided portion includes the The guided portion is supported by the guide member in a state in which the wire of the guide member is inserted.

Driftwood, dust, etc. will not enter between the guided portion and the guide member and become clogged. For this reason, the floating body can ascend and descend reliably following the fluctuation of the water level.

請求項3に記載の発明によれば、リング状の被ガイド部にガイド部材の線材が挿入された状態で被ガイド部がガイド部材で案内、支持されているため、被ガイド部と線材との隙間を適正化することで、浮遊体の浮遊自由度が高まる。このため、浮遊体に流木などが付着した際に、浮遊体やガイド部材にかかる応力を緩和させることができる。また、被ガイド部がリング状で、ガイド部材が線材で構成されているため、装置の構成を簡素化でき、製造コストも低減できる。   According to the third aspect of the present invention, since the guided portion is guided and supported by the guide member in a state where the guide member wire is inserted into the ring-shaped guided portion, the guided portion and the wire By optimizing the gap, the floating freedom of the floating body increases. For this reason, when driftwood etc. adhere to a floating body, the stress concerning a floating body and a guide member can be relieved. Moreover, since the guided portion is ring-shaped and the guide member is made of a wire, the configuration of the apparatus can be simplified and the manufacturing cost can be reduced.

以下、本発明を図示の実施形態に基づいて説明する。   Hereinafter, the present invention will be described based on the illustrated embodiments.

図1は、本発明の実施形態に係わる網場装置1(浮遊体装置)を示す概略構成図である。この網場装置1は、河川R(流水)に浮いた状態で配設される網場2(浮遊体)と、ガイドワイヤ3(ガイド部材、線材)と、昇降装置4とを備えている。   FIG. 1 is a schematic configuration diagram showing a network device 1 (floating body device) according to an embodiment of the present invention. This netting device 1 includes a netting field 2 (floating body) disposed in a floating state on a river R (running water), a guide wire 3 (guide member, wire), and an elevating device 4.

網場2は、図2に示すように、2つの取水口ピラーPの間に配設された取水口スクリーンSの前方(上流側)に配設されている。この網場2は、図3に示すように、梯子状の枠体21の両端部に浮き袋22が取り付けられ、網場2の前面2aが河川Rの上流側に位置し、この前面2aと対向する背面2bが河川Rの下流側(取水口スクリーンS側)に位置するように配設されている。そして、河川Rの上流側から流れてきた流木や塵芥などの流れを網場2の前面2aによって留め、流木や塵芥などが取水口スクリーンS側に流れ込むのを防止するものである。この網場2の両端部の背面2b中央部には、リング状のガイドリング23(被ガイド部)が取り付けられ、各ガイドリング23にガイドワイヤ3が挿入されている。すなわち、ガイドワイヤ3は取水口ピラーPに沿って上下方向に延びて配設され、上下端部がアンカーフック31を介して取水口ピラーPに固定されている。このようなガイドワイヤ3がガイドリング23に挿入されて、ガイドリング23が支持されるとともに、上下方向に案内されるようになっている。また、この状態で、ガイドワイヤ3が網場2の背面2b側に位置する(網場2の前面2aで隠れる)。そして、このようなガイドワイヤ3とガイドリング23とによって、網場2がガイドワイヤ3に沿って昇降できる、あるいは、網場2が流されないようになっている。   As shown in FIG. 2, the net 2 is disposed in front (upstream side) of the intake screen S disposed between the two intake pillars P. As shown in FIG. 3, a floating bag 22 is attached to both ends of a ladder-like frame body 21, and the front surface 2a of the network field 2 is located on the upstream side of the river R, and is opposite to the front surface 2a. The rear surface 2b is disposed on the downstream side of the river R (the intake screen S side). Then, the flow of driftwood, dust and the like flowing from the upstream side of the river R is stopped by the front surface 2a of the net 2 and the driftwood, dust and the like are prevented from flowing into the intake screen S side. A ring-shaped guide ring 23 (guided portion) is attached to the center of the back surface 2 b of both ends of the net 2, and the guide wire 3 is inserted into each guide ring 23. That is, the guide wire 3 is disposed so as to extend in the vertical direction along the intake pillar P, and the upper and lower ends are fixed to the intake pillar P via the anchor hooks 31. Such a guide wire 3 is inserted into the guide ring 23 so that the guide ring 23 is supported and guided in the vertical direction. Further, in this state, the guide wire 3 is located on the back surface 2b side of the network field 2 (hidden by the front surface 2a of the network field 2). The net field 2 can be moved up and down along the guide wire 3 by the guide wire 3 and the guide ring 23, or the net field 2 is prevented from flowing.

昇降装置4は、図4に示すように、各取水口ピラーPの頂部P1に一台配設され、フレーム41と、ウインチ42と、固定滑車43と、移動滑車44と、アイナット45(固定手段)とを備えている。フレーム41は、取水口ピラーPの頂部P1に垂直に設置された第1フレームピラー411と第2フレームピラー412と、このフレームピラー411、412の頂部に架設された水平アーム413から構成されている。また、図5に示すように、第2フレームピラー412は2本のピラー材412a、412bから構成されている。水平アーム413の先端部は河川R側に臨み、滑車取付フック413aが取り付けられている。さらに、水平アーム413の第1フレームピラー411と第2フレームピラー412との間には、ウインチカバー413bが設けられ、このウインチカバー413b内にウインチ42のウインチ本体421が取り付けられている。   As shown in FIG. 4, one lifting device 4 is disposed at the top P <b> 1 of each intake pillar P, and includes a frame 41, a winch 42, a fixed pulley 43, a movable pulley 44, and an eye nut 45 (fixing means). ). The frame 41 includes a first frame pillar 411 and a second frame pillar 412 that are vertically installed on the top P1 of the water intake pillar P, and a horizontal arm 413 that is installed on the top of the frame pillars 411 and 412. . As shown in FIG. 5, the second frame pillar 412 is composed of two pillar members 412a and 412b. The tip of the horizontal arm 413 faces the river R side, and a pulley mounting hook 413a is attached. Further, a winch cover 413b is provided between the first frame pillar 411 and the second frame pillar 412 of the horizontal arm 413, and the winch body 421 of the winch 42 is attached in the winch cover 413b.

このウインチ42のワイヤ422が移動滑車44および固定滑車43にかけられ、その先端部(自由端部)が網場2の端部に取り付けられている。すなわち、固定滑車43は滑車取付フック413aに取り付けられ、これによりその位置が固定されている。また、移動滑車44は滑車本体441とフック442とを備え、第2フレームピラー412のピラー材412a、412bの間に配設され、ワイヤ422によって宙に浮いた状態となっている。これにより、後述するように、網場2が昇降するのに伴って、あるいはワイヤ422が巻き上げ、巻き下げられるのに伴って、移動滑車44が上下方向に移動できるようになっている。さらに、移動滑車44の重量は、ワイヤ422を常時張った状態にするのに要する重量(荷重)に設定されている。そして、このような移動滑車44と固定滑車43とを介して、ワイヤ422の先端部が網場2に取り付けられているものである。   The wire 422 of the winch 42 is hooked on the movable pulley 44 and the fixed pulley 43, and the tip (free end) thereof is attached to the end of the net 2. That is, the fixed pulley 43 is attached to the pulley attachment hook 413a, and the position thereof is fixed. The movable pulley 44 includes a pulley body 441 and a hook 442, is disposed between the pillar materials 412 a and 412 b of the second frame pillar 412, and is in a state of being suspended in the air by the wire 422. Thereby, as will be described later, the movable pulley 44 can move in the vertical direction as the net 2 is moved up and down, or as the wire 422 is wound up and down. Furthermore, the weight of the movable pulley 44 is set to a weight (load) required to make the wire 422 always stretched. The tip of the wire 422 is attached to the net 2 via the movable pulley 44 and the fixed pulley 43.

アイナット45は、基部451とリング部452とを備え、基部451がピラー材412a、412bの間の取水口ピラー頂部P1に打ち止めされている。そして、移動滑車44を取水口ピラーPの頂部P1側に位置させて、フック442をアイナット45のリング部452にかけることで、移動滑車44の位置が固定されるものである。   The eye nut 45 includes a base portion 451 and a ring portion 452, and the base portion 451 is fixed to the water intake pillar top portion P1 between the pillar members 412a and 412b. Then, the movable pulley 44 is positioned on the top P1 side of the water outlet pillar P, and the hook 442 is hooked on the ring portion 452 of the eye nut 45, whereby the position of the movable pulley 44 is fixed.

次に、このような構成の網場装置1の作動について説明する。   Next, the operation of the network device 1 having such a configuration will be described.

上記のように網場2が河川Rに浮いている状態で、例えば、河川Rの水位が上ると、図6に示すように網場2も上昇し、網場2側のワイヤ422も上昇する。これにより、ウインチ本体421と固定滑車43との間のワイヤ422の長さが長くなり、移動滑車44が自重によって下方に移動するとともに、移動滑車44の重量によってワイヤ422が張られる。このとき、網場2のガイドリング23がガイドワイヤ3によって支持、案内されながら、網場2がガイドワイヤ3に沿って上昇する。   For example, when the water level of the river R rises in a state where the net 2 is floating in the river R as described above, the net 2 is also raised as shown in FIG. 6, and the wire 422 on the net 2 is also raised. . Thereby, the length of the wire 422 between the winch main body 421 and the fixed pulley 43 becomes long, the moving pulley 44 moves downward by its own weight, and the wire 422 is stretched by the weight of the moving pulley 44. At this time, the net 2 rises along the guide wire 3 while the guide ring 23 of the net 2 is supported and guided by the guide wire 3.

一方、河川Rの水位が下がると、図7に示すように網場2も降下し、網場2側のワイヤ422も降下する。これにより、ウインチ本体421と固定滑車43との間のワイヤ422の長さが短くなり、ワイヤ422の移動によって移動滑車44が上方に移動する(押し上げられる)とともに、移動滑車44の重量によってワイヤ422が張られる。このとき、網場2のガイドリング23がガイドワイヤ3によって支持、案内されながら、網場2がガイドワイヤ3に沿って降下する。   On the other hand, when the water level of the river R falls, the net 2 is also lowered as shown in FIG. 7, and the wire 422 on the net 2 side is also lowered. As a result, the length of the wire 422 between the winch body 421 and the fixed pulley 43 is shortened, and the moving pulley 44 is moved upward (pushed up) by the movement of the wire 422, and the wire 422 is driven by the weight of the moving pulley 44. Is stretched. At this time, the mesh field 2 descends along the guide wire 3 while the guide ring 23 of the mesh field 2 is supported and guided by the guide wire 3.

また、網場2に付着した流木や塵芥などを取り除くなどのために、網場2を水面よりも上昇させるには、次のようにすればよい。すなわち、ウインチ本体421を巻き下げ方向に作動させて移動滑車44をアイナット45まで移動(下降)させ、図8に示すように、フック442をリング部452にかけて移動滑車44を固定させる。この固定によって移動滑車44が固定滑車として機能し、この状態でウインチ本体421を巻き上げ方向に作動させればよい。これにより、移動滑車44および固定滑車43を介してワイヤ422が巻き上げられ、網場2が水面よりも上昇する。また、流木の取り除き作業などが終了した後に網場2を河川Rに戻すには、ウインチ本体421を巻き下げ方向に作動させればよい。これにより、移動滑車44および固定滑車43を介してワイヤ422が巻き下げられ、網場2が水面に位置される。   In order to raise the net 2 above the water surface in order to remove driftwood or dust attached to the net 2, the following may be performed. That is, the winch body 421 is actuated in the lowering direction to move (lower) the movable pulley 44 to the eyenut 45, and the movable pulley 44 is fixed by applying the hook 442 to the ring portion 452 as shown in FIG. By this fixing, the movable pulley 44 functions as a fixed pulley, and the winch body 421 may be operated in the winding direction in this state. Thereby, the wire 422 is wound up via the movable pulley 44 and the fixed pulley 43, and the net 2 is raised above the water surface. Further, in order to return the net 2 to the river R after completion of the work of removing driftwood, the winch body 421 may be operated in the lowering direction. Thereby, the wire 422 is wound down via the moving pulley 44 and the fixed pulley 43, and the net 2 is located on the water surface.

このように、本網場装置1によれば、ガイドワイヤ3とガイドリング23とが網場2の背面2b側に位置し、上流側からの流木や塵芥などは網場2の前面2aで留められるため、流木や塵芥などがガイドワイヤ3とガイドリング23との間に入り込み、詰まってしまうことがない。このため、網場2が河川Rの水位の変動に追従して確実に昇降できる。また、移動滑車44の移動可能距離を例えば2mとすることで、最大4mの水位変動に追従することができ、網場装置1(昇降装置4)の高さを低く抑えて、大きな水位変動に追従することができる。   As described above, according to the network device 1, the guide wire 3 and the guide ring 23 are located on the back surface 2 b side of the network field 2, and driftwood and dust from the upstream side are fastened on the front surface 2 a of the network field 2. Therefore, driftwood, dust, and the like do not enter between the guide wire 3 and the guide ring 23 and become clogged. For this reason, the net 2 can move up and down reliably following changes in the water level of the river R. Moreover, by setting the movable distance of the movable pulley 44 to 2 m, for example, it is possible to follow a maximum water level fluctuation of 4 m, and to suppress the height of the netting device 1 (elevating device 4) to a large level. Can follow.

しかも、ガイドリング23にガイドワイヤ3が挿入された状態でガイドリング23がガイドワイヤ3で案内、支持されているため、ガイドワイヤ3とガイドリング23との隙間を適正化することで、網場2の浮遊自由度が高まる。このため、網場2の流木などが付着した際に、網場2やガイドワイヤ3にかかる応力を緩和させることができる。また、リング状のガイドリング23と、線材であるガイドワイヤ3とで構成されているため、網場装置1の構成を簡素化でき、製造コストも低減できる。   In addition, since the guide ring 23 is guided and supported by the guide wire 3 in a state where the guide wire 3 is inserted into the guide ring 23, the gap between the guide wire 3 and the guide ring 23 is optimized, and the network 2's degree of freedom of floating increases. For this reason, when the driftwood of the mesh field 2 adheres, the stress concerning the mesh field 2 and the guide wire 3 can be relieved. Moreover, since it is comprised by the ring-shaped guide ring 23 and the guide wire 3 which is a wire, the structure of the network apparatus 1 can be simplified and manufacturing cost can also be reduced.

さらに、アイナット45で移動滑車44を固定させ、ウインチ本体421を作動させるだけで、網場2を水面から昇降させることができる。すなわち、水上かつ高所でのフックの掛け替えなどを要しない。このため、安全かつ容易に網場2を水面から昇降させることができる。また、水位の変動に係わらず、移動滑車44の重量によってワイヤ422が常に張られた状態となり、ワイヤ422がたるんで網場2や固定滑車43などにワイヤ422が絡むことなどが防止される。さらに、昇降装置4が各取水口ピラーPの頂部P1に配設され、網場2の両端部にそれぞれワイヤ422が取り付けられているため、網場2全体が水平に昇降する。このため、網場2の一端部のみを上げる片上がりの状態に比べて、網場2に付着した流木や塵芥などをすべてかつ容易に取り除くことができる。   Furthermore, the net 2 can be raised and lowered from the water surface simply by fixing the movable pulley 44 with the eye nut 45 and operating the winch body 421. That is, there is no need to change hooks on the water and at high places. For this reason, the net 2 can be raised and lowered from the water surface safely and easily. Regardless of the fluctuation of the water level, the wire 422 is always stretched due to the weight of the moving pulley 44, and the wire 422 is prevented from sagging to prevent the wire 422 from being entangled with the net 2 or the fixed pulley 43. Furthermore, since the lifting device 4 is disposed at the top P1 of each intake pillar P, and the wires 422 are attached to both ends of the mesh field 2, the entire mesh field 2 moves up and down horizontally. For this reason, it is possible to easily remove all driftwood, dust, and the like attached to the net 2 as compared to a one-side-up state where only one end of the net 2 is raised.

以上、この発明の実施形態について説明したが、具体的な構成は、本実施形態に限られるものではなく、この発明の要旨を逸脱しない範囲の設計の変更等があっても、この発明に含まれる。例えば、本実施形態では、アイナット45を取水口ピラーPの頂部P1に設け、移動滑車44を常に頂部P1で固定するようにしているが、任意の位置で固定するようにしてもよい。すなわち、例えば、第2フレームピラー412のピラー材412a、412bに垂直方向に沿って複数の挿入孔を設け、任意の挿入孔に止め棒を挿入する。そして、この止め棒にフック442をかけることで移動滑車44を固定するようにしてもよい。これにより、網場2を水面よりも上昇させる度に、移動滑車44をアイナット45まで移動させる必要がなくなる。   Although the embodiment of the present invention has been described above, the specific configuration is not limited to the present embodiment, and design changes and the like within a scope not departing from the gist of the present invention are included in the present invention. It is. For example, in this embodiment, the eye nut 45 is provided at the top P1 of the water outlet pillar P and the movable pulley 44 is always fixed at the top P1, but it may be fixed at an arbitrary position. That is, for example, a plurality of insertion holes are provided along the vertical direction in the pillar members 412a and 412b of the second frame pillar 412, and a stop bar is inserted into an arbitrary insertion hole. Then, the movable pulley 44 may be fixed by hooking the hook 442 to the stop bar. Thereby, it is not necessary to move the moving pulley 44 to the eye nut 45 every time the net 2 is raised above the water surface.

ところで、本実施形態では、網場2が浮遊体とされているが、油フェンスや貯水池水温計などその他の浮遊体であってもよいことは勿論である。   By the way, in this embodiment, the net 2 is a floating body, but it is needless to say that other floating bodies such as an oil fence and a reservoir thermometer may be used.
